Daily Light Integral (DLI) Calculator for Optimal Plant Growth

Calculate Your Plant's Daily Light Integral

Effortlessly calculate the Daily Light Integral (DLI) for your plants. This tool helps horticulturists, growers, and enthusiasts determine the total amount of light received by plants each day, crucial for healthy development. Simply input your Photosynthetic Photon Flux Density (PPFD) and light duration to get instant results.

Formula:

The Daily Light Integral (DLI) is calculated using the following formula:

DLI (mol/m²/day) = (PPFD (µmol/m²/s) × Photoperiod (hours) × 3600 (seconds/hour)) / 1,000,000 (µmol to mol)

Where:

  • DLI: Daily Light Integral
  • PPFD: Photosynthetic Photon Flux Density
  • Photoperiod: Duration of light exposure
